BAND-SAW GUIDE.

Application filed February To all rv/10m it may concern:

Be it known that I, Jncor, RUSH. acitizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentacky, have invented certain new and useful improvements in a Band-Saw Guide of which the following is a specification.

The present invention relates to guides for band saws used in wood working and. other analogous arts, and its prime object is to provide a guide for a band-saw which is easily, readily, and quickly adjustable.

Another important cbiect of the inven tion is to provide a guide of this nature having independent adjustments for the retary disk guide and the side guide,

A further specific object of the invention is to provide a main supporting block having adjustably mounted therein a rotary guide disk and a side guide supporting block.

A still further important object of the invention is to provide a device of this nature having an efficient and simple structure which is free from friction as it is p r ssible, and which is strong, durable, inexpensive to construct, and not liable to readily get out of order, reliable in use, and otherwise well adapted to the purpose for which it is designed.

(Fit 1 the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction and in thecombination and arrangement of parts that will be hereinafter more fully described and claimed.

1n the drawing Figure 1 is a front elevation of the guide embodying the features of my invention,

Fig. 2 is a side elevation thereof,

Fig. 3 is a section thercthrough taken sub stautially on the line -:33, of Fig. 1,

'-lis a section taken on the line 47-4 of Fig. 2 in the direction of the arrow,

Fig; 5 is a section taken on the line 5 5 of Fig. 4, looking in the direction of the arrow on a smaller scale,

Fig. 6 is a detail perspective view of one of the side guides, and

Fig. 7 is a plan view of the adjustable block for the side guide.

Referring to the drawing in detail it will be seen that a suitable supporting stem or 10, 1925. Serial No. 8,172,

rod 5 is provided by which this improved guide is secured in its proper position upon the band-saw machine in the position where desired. On this rod 5, at the end thereof, a fixed block 6 is mounted having therein an opening 7 and a parallelly ext-ending opening 8. These openings extend transversely through the block 6. Thumb screws 9 and 10 are threaded through the block 6 to enter the openings 7 and 8 respectively.

A socket or sleeve 12 is slidablv mounted through the opening 7 and held in adjusted position by the thumb screw 9. The spindle 3 of a rotary guide disk lt is journaled in the socket or sleeve 12 and is adapted to bear against the plain edge of the bandsaw here indicated by the letter A.

An adjustable or movable guide supporting block 15 is disposed'in parallelism with the fixed block 6. A pair of pins 16 project perpendicularly from the block 15 and extends through openings 17 provided therein and through the openings 8 of the stationary block 6. The thumb screws 10 engage these pins 16 and hold them a'djusted in relation to the fixed or stationary block 6. Thumb screws 18 extend through the block 15 and enter the openings 17 to engage stems or pins 16 so as to hold these I pins in adjusted positions in relation to the adjustable block 15. This adjustable block 15 is provided with an enlarged opening 20 through which projects the socket 12 and a recess 21 in which is located the disk guide 1%.

The face of the block 15 which is disposed farthest from block 6 is provided with a pair of alined mortises or grooves 24 one adjacent each side thereof and a pair ,stud bolts 25 one adjacent each mortise or groove 24. A pair of side bearing guides 26 are disposed on said face of the block 15 each being substantially U-shaped in formation as is disclosed to advantage in Fig. 6 having a tenon or tongue 27 projecting from one face to move in the respective mortise or groove 24 of the movable block 15 and a notch 28 for receiving the respective stud bolt 25. In the present embodiment of the invention the stud bolts 25 are in the form of screws as is shown to advantage in Fig. 1, receivable in the openings 25 in the block 5 and by tightening these screws the bearing guides 26 may be held at different distances from each other. -T he ends of the guldes 26 are adapted to be disposed adjacent each other and are provided with plates 29 held in place by screws or the like 30 which will engage the sides ofthe saw-band.

It will thus be seen that the disk 14; may 2e adjusted so as to be disposed between the side guides 26 such as is indicated in Fig. 4.

In using. my device it will be seen that it ispossible to first adjust the rotary disk guide 14 so as to engage the plain edge of the band-saw A after which the block 15 -m'ay be: adjusted. and then the guides 26.

These different adjustments may be made independently of each other so that there is perfect accuracy and one adjustment in no way interferes with the other. It is ap parent from the descriptionof this device that it possesses a very easily manipulated adjustment which insures accuracy and the saving of considerable time.

It will be further apparent that the embod'iment of the invention which I have disclosed herein contains the features of advantage enumerated as desirable in the statement of the invention and the above description and that numerous changes in the details of construction, and in the combination and arrangementof parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed.

Having thus described my invention,

posed the rotary disk guide, a pair of side guide" members adjustably mounted on the movable blocks. 7

2.111 a band saw guide, a stationary block, a movable guide supporting block, a pair of pins slidable through the blocks,

means for locking the pins in adjustment with the blocks, a socket extending through the fixed block, means for holding the socket in adjusted positions in relation to the fixed block, a rotary disk guide having a spindle in the socket, said movable block provided with an opening: in which is disposed the rotary disk guide, a pair of side guide members adjustably mounted on: the movable blocks, each side" guide member being U-shaped in formation and having bearing plates at its ends. 7

In testimony whereof I aflix my signature.
